Question 16

what kind of movement is possible in the cervical portion of the spine?

Answer 16

extension
flexion
lateral flexion
rotation occurs from the atlantoaxial joint

most flexible

Question 17

what kind of movement is possible in the thoracic region of the spin?

lateral flexion
some extension
some rotation
flexion

presence of ribs inhibits motion some

Answer 18

some extension
flexion
no rotation
little lateral flexion

Answer 21

uncinate processes

Question 22

plane of the zygaphophyseal joint determins what?

Answer 22

possiblity for movement

Question 23

the anterior longitudinal ligament has what effect on movement?

Answer 23

limits extension

Question 24

the posterior longitudinal ligament has what effect on movement?

Answer 24

limits flexion

herniation of the nucleus pulposus is related to the weakening of what ligament?

Answer 25

weakening of the posterior longitudinal ligament

-posterior longitudinal ligament is associated with the “diskal” spaces
